The director and main actor is Shane Carruth, an ex-engineer who also wrote the script, and made the music! His family and friends make most of the cast, too!
Carruth is a scientist by formation. Therefore, all the part of the story related to the experimentation and discussions taken part in the garage are truly believable as they have all the technical jargon that you expect from real physicists. If time-travel was discovered would be, we can guess, in a similar way to the one portrayed in the movie.
The use of the camera and the amateurish acting (really pedestrian in the case of Carruth) help the story to be credible, down to earth and realistic. As if somebody was filming the meetings and wanderings of the characters with a video-camera. Something very close to reality to what went on in Carruth's house when he was preparing and shooting the movie.
The movie is definitely original, believable and refreshing, and incredibly good-looking for the low budget. A good suit and a tie always work on camera! The 1990s mood and style are very good. The mobiles and the computers range between the mid 1980s and mid 1990s, and the laptop in the movie is very similar to my first (and now ancient MS2) Toshiba.
The first and main problem of the movie, to me, is not the jargon, but the fact that the dialogues are crowded, words colliding atomically against others at the speed of light. Moreover, the diction of the actors, especially of the two main characters, is really bad, a fact that is highlighted by the poor quality of the sound. Secondly, there are gaps and blurs not well explained in the script, or perhaps are just the result of a poor editing. In general, the movie is a bit thick and confusing.
The movie won the Prize of the Jury and the Alfred P. Sloan Prize at Sundance 2004, but I do not think the first one was deserved - my opinion.
The first time I wrote about this movie, I ended saying:
Well, he has proven to continue to showcase his talent, and wrote the scripts for two other science-fiction movies: the critically well-received "Looper" and for the just released and winner of the Special Prize of the Jury at Sundance 2013, "Upstream Colour".Carruth is somebody to watch in the future and has brilliant ideas. Hopefully, he will have enough budget next time, and will have learnt better film-making skills, so he can make a great film that is not just for scientists doing a Ph.D. and without having to sacrifice any depth. That's possible. You need to learn film-making, not just produce your own brilliant ideas.
